Question

Each molecule in a gas has an average kinetic energy. What is the total average kinetic energy of all the molecules in 5.26 mol of a gas whose temperature is 387K?

Answer #1

According to Kinetic Molecular Theory, the average kinetic energy of gas molecules is a function only of temperature.

K.E is the average kinetic energy, k is the boltzmann constant and T is the temperature

For a mole of molecules, the average kinetic energy is,

Average kinetic energy for 5.26 moles of gas is,

(Ans)

The average kinetic energy of the molecules in a gas sample
depends only on the temperature, T. But given the same kinetic
energies, a lighter molecule will move faster than a heavier
molecule.
